Explain what we mean when we say that two filters are cascaded.

Create a filter to remove noise from a signal (for example, a low pass filter or a band pass filter). you can use any input signal.Use Scilab 1)Problem Statements.2) Simulation.3) Result.4)Conclusion.

We apply a 5-V-rms 20-kHz sinusoid to the input of a first-order RC lowpass filter, and the output voltage in steady state is 0.5 V rms. Predict the steady-state rms output voltage after the frequency of the input signal is raised to 150 kHz and the amplitude remains constant.

i know b and d is true, idk about the rest

CR active filters find extensive use in communications and instrumentation measurements. a) By considering how the capacitor impedance in Figure 1 varies with frequency, explain if the circuit in Figure 1 acts as a low-pass or high-pass filter. p) Derive the closed-loop gain for the case of very high frequencies. c) Draw a graph that shows the frequency response of the CR active high-pass filter. The y-axis should correspond to gain in dBs and the x-axis to frequency. Make sure that you clearly indicate the 3 dB point and the equation that describes the relationship between w and CinRin at the cut-off frequency. Cin Rin A Vin Vout Figure 1
